SO it sounds like Rain X is out.
I am doing some surf work coming up. What do you all suggest to fight water spots on Acrylic domes? I cant just wipe it down as I will be in the surf line and there will be a lot of suspended sand. Any ideas?

What about the same stuff we put in masks to stop fogging?

Rainx makes (or made) a product for acrylic and you can get it at Marine stores. I use a defogger called Defogit and it works OK. Better than mask defog for sure.

I've used spit. But it takes quite a bit of it... :-)

Please do not press the shutter button while licking your dome. That is NOT a pleasant picture. (Look honey, it's the frobulous pink sea cucumber octofish, it just swam right up onto my dome! Those little buds are all its tiny little feet....)

Current rig: Sony SLT-alpha55 in Ikelite housing, Sigma 105mm f2.8 DC Macro w/ Ike 5505.58 flat port or Sigma 8-16mm f/4.5-5.6 DC HSM behind UWCamStuff custom 5" mini-dome. Dual INON z240 Type IVs triggered with DS51 for TTL mimicry, or DS51 alone with home-made ringflash assy for macro.

 

Topside, unhoused: Sony SLT-alpha99, Sigma 150-500mm + 1.4TC (Saving for Sony 70-400 G2), Sigma 15mm diagonal fish, Sony 24-70mm f2.8 CZ, Tamron 180mm f2.8 Macro...all the gear and nary a clue...

I saw the other day at a gas station polishing wax and shining wax (both for metal and plastic). The shining one is also water repellent so it would be worth a try for split shots, something like this:

Raw potato slices seems to work well, but may be difficult to carry in the surf and
you have to rub the dome with them ....

After a little searching I found that Ceebailies Water Repelant Max. It is a motorcycle and aircraft windshield water repelant.

Johnson & Johnson's baby shampoo. Use either straight from the bottle or dilute with water.

New to all this, I am assuming and ready between the lines, Rain X is corrosive to acrylic? I have just ordered a 8" dome from Ikelite and believe its acrylic, so will try the shampoo...

Rain-X seems to use isopropanol (or a similar solvent) as as carrier, which can attack some plastics.  I have used it in helmet face shields with good results, but I know of others who have had serious problems with the Rain-X attacking the plastic.  The CeeBailey's product sounds as if it might be a good solution, but I have not tried it myself.

Thanks for the clarification SwiftFF5 I will see if there is any over this side of the pond.
